Urinary bladder metastasis from breast cancer: A rare case report

Breast cancer is a major contributor to cancer-related morbidity and mortality in women, which is primarily attributed to metastases. Common metastatic sites include the lungs, liver, and bone, whereas bladder metastasis is rare. We report a case of bladder metastasis from breast cancer in a 61-year-old woman, highlighting the challenges in diagnosis and treatment. The patient, previously diagnosed with invasive lobular carcinoma, presented with renal failure and underwent transurethral resection of bladder tumor. Pathological analysis confirmed metastasis from breast cancer. Bladder metastasis from breast cancer demands vigilance and prompt intervention because of its potential prognostic impact.
